ANTICBEEPER.

Application filed March 12. 1920.

'0 all oo/ 20m it may concern: v

Be it known that I, DAVID L. AUGHAn, a citize of the United residing atlliv crtoin the county of Burlington and State New Jersey, have inventedcertain new ant useiul Improvements in Anticrcepers, of which thefollowing is a specification.

The object of my invention is to provide a novel, simple and efficientanti reaping device for railroad rails wherein the device is formed ofspring metal and is provided with spaced end bearing or rail grippingparts at an intermediate bearing or rail o a s at. oted to be sprungfrom its normal condition by parts of the railroad structure to engagethe spaced and intermediate bearing parts of the device with a rail baseand to cause the spaced end bearing oar-ts to be held in grippingengagement with the rail base by the tendency of the device to resumeits normal condition wnile the means which holds the spring device inplace holds the intermediate bearing part or parts thereof in grippingengagement with the rail base.

With the above and related objects in view. the invention consists ofthe elements and the combinations of them hereinafter described andclaimed.

In the accompanying drawings, illustrating the invention,

Figure 1 is a top view of a part of a railroad structure provided withan anticreeping device embodying my invention.

Fig. 2 is an elevation of, the parts shown in Fig. 1, showing therailroad rail in ection.

Fig. 3 is a perspective view of the spring anti-creeping device. I

Fig. 4 is a sectional detail on line 4--1 of Fig. 2.

his. 5 is a perspective view of modified form of the spring anticreepingdevice.

Referring to the drawings, 2 designates portion of a r ilroad cross tie,3 a tie plate ther on and at a portion of a railroad rail supported uponthe tie plate.

T he tie plate 3 is provided with a rib which is engaged by one side ofthe rail has 6 and prevents lateral displacement of the rail d by thethrust of wheel flanges against the opposite side thereof.

The rail 4 and tie plate 3 are held down upon the cross tie 2 by theusual spikes 7 and 8 which are driven through holes 9 and 10,respectively, in the plate 3 and into the cross Specification of LettersPatent.

tie 2, and the heads of which engage the top of the rail base 6. Theplate 3 is also provided with a spike hole 11 to receive a spike similarto the spike 8 to perform the same function performed thereby. The spike7 assists the rib 5 in preventing lateral displacement of the rail 4 inone direction, and the spike 8, together with a similar spike driventhrough the hole 11 and into the cross tie 2, prevents lateraldisplacement of the rail 4 in the opposite direction.

The parts thus far described and the functions which they perform arewell known in this art and no detailed description thereof is deemednecessary herein.

My improved anticreeping device 12 is associated with the partspreviously described and by cooperation therewith prevents the rail lfrom creeping under the well known conditions which cause such action.

The anticreeping device 12 is formedof spring metal, one 12 beingadapted to be interposed between the spike 8 and the adjacent edge ofthe rail base 6,'and another 12 being adapted to be interposed betweenthe rail base 6 and a spike driven through the hole 11 and into thecross tie 2.

The end portions 13 of the device 12 are made wider than the centralportion 14 thereof, the device gradually widening from its centralportion 14 to its end portions 13 to provide oppositely-directed,wedge-like end por ions, as clearly shown in the drawings, for a purposehereinafter explained.

One side of the device 12 is provided with row of teeth 15 which extendsfrom end to end thereof, and in the normal condition of the device, asshown in Fig. 3, and at 12 in Fig. 1, the central teeth 15 of the roware back of a straight line which extends between the end teeth 15 ofthe row. In other words, when the device, in its normal condition, isplaced against the edge of one side of the rail base 6 with the endteeth 15 of the row against the rail base edge, the cen tral teeth 15 ofthe row will be back or spaced from the edge, as shown at 12 in Fig. 1;and the rail base edge may thus represent the straight line abovereferred to.

In applying the anticreeping device to a rail, the device is placed uponthe tie plate 3 with the end teeth 15 of the row thereof against therail base edge and with the central portion of the device over a part ofa spike hole in the plate, as shown at 12 in Fig. 1. A spike, such asthe spike 8, is then driven through the hole and into the cross tieagainst the outer face of the anticreeping device and the opposing wallof the spike hole. This operation will cause the spike to spring thedevice from its normal condition by pressing the central portion thereoftoward the rail base until the device assumes the condition shown inFig. 4: and at 12 in Fig. 1, wherein the central teeth 15 of the row areforced into gripping engagement with the rail base 6 by the directpressure of the spike, and the outer or end teeth 15 are forced intogripping engagement with the rail base by the spring action of thedevice in tending to resume its normal condition.

Then the device is thus applied, the teeth 15 thereof embed themselvesin the rail base edge, as illustrated, and the wide or wedgelike endortions '13 extend beyond the sides of the spike, so that any tendencyof the rail to creep will tend to draw one of the wedgelike end portions13 between the spike and the rail base and thus prevent the rail fromcreeping relatively to the tie plate 3 and the cross tie 2 whichconstitute stationary parts of the road bed supporting the rail 4:.

The anticreeping device is held against vertical displacement relativelyto the rail base by and between the head of the spike engaged therewithand the underlying tie plate.

In Fig. 5 l have shown a modification wherein the anticreeping device 12is provided with two end bearing teeth 16 and one intermediate orcentral tooth 17 in lieu of the row of teeth 15 shown in Fig. 3. In allother respects the device shown in Fig. 5 is like the device shown inFig.

I claim as my invention 2- 1. The combination with a railroad rail and astationary part of a road bed supporting the rail, of an anticreepingdevice formed of spring metal and having two spaced hearing parts and anintermediate bearing part back of a straight line drawn between saidspaced parts in the normal conditionof said device, and means on saidstationary part holding said device sprung from its normal conditionwith its three bearing parts engaged with the base of said rail. 7

2. The combination with a railroad rail and a stationary part of a roadbed supporting the rail, of an anticreeping device formed of springmetal and having two spaced bearing parts and an intermediate bearingpart back of av straight line drawn between said spaced parts in thenormal condition of said device, and means on said stationarypartholding said device sprung from its normal condition with its threebearing parts engaged with the base of said rail, said device having awedge shaped portion adapted to prevent the movement of the devicebetween the rail base and said means when the rail tends to creep.

The combination with a railroad rail and a stationary part of a road bedsupporting the rail, of an anticreeping device formed of spring metaland having a row of bearing teeth on one side thereof, the intermediateteeth of the row being back of a straight line drawn between the endteeth of the row in the normal condition of said device, and means onsaid stationary part holding said device sprung from its normalcondition with all the teeth of said row engaged with the base of saidrail.

4. The combination with a railroad rail and a stationary part of a roadbed supporting the rail, of an anticreeping device formed of springmetal and having a row of bearing teeth on one side thereof, theintermediate teeth of the row being back of a straight line drawnbetween the end teeth of the row in the normal condition of said device,and means on said stationary pr t holding said device sprung from itsnormal condition with all the teeth of said row engaged with the base ofsaid rail, said device having a wedge shaped portion adapted to preventthe movement of the device between the rail base and said means when therail tends to creep.

5. An anticreeping device formed of spring metal and having end portionswider than the central portion thereof and having a row of bearing teethon one side thereof, the intermediate teeth of the row being back of astraight line drawn between the end teeth of the row, and said devicebeing adapted to be sprung from its normal condition to cause all theteeth of the row to engage a rail base and to cause the end teeth of therow to press againstthe rail base by the tendency of the device toresume its normal condition.

In testimony whereof I till my signature hereto;

DAVID L. VAUGHAN.
